Hints for determining the type of axle: Dana 80 axles were only used on E-Series units where the 5th position of the VIN is "E" and the 6th position of
the VIN is "4" (E40, E45, E47, E49). The parking brake position also provides a way to ensure, that you are working on an E-450. All E-450s have the
parking brake at the back of the transmission on the driveshaft. If there is not a parking brake assembly on the driveshaft, the vehicle being worked on is
not an E-450 and this TSB does not apply.
